1. System Overview

The Thermaco, Inc. Trapzilla® Supercapacity
Grease Interceptor collects free-floating
grease & oils contained in kitchen drain water

ows. As most food service facility managers

already know, grease buildup inside a
building’s grease containment system is a
major cause of problems due to exterior drain
line blockages. These problems jeopardize
normal operations as well as create health
and safety hazards within the facility itself.

The proper installation of a Trapzilla®
Supercapacity Grease Interceptor can
reduce or eliminate grease problems and

costly sewer surcharges and nes through
efcient separation and retention of free­oating grease & oils.

The Trapzilla offers patented at separation
curve technology. This means that the unit does not lose grease separation efciency as it lls with
retained grease. Thus, the Trapzilla stores large quantities of grease without losing efciency. The

unique compact design of the Trapzilla allows for installation into most facilities. Options are available

that enable a Trapzilla unit to be installed on the oor, suspended from the ceiling or in-ground outside

the facility.

Trapzilla units are designed to treat high ows of kitchen drainwater with large grease storage capacity

within a small footprint unit. These units are easy to maneuver into position and just as easy to plumb.

Hydromechanical grease interceptors, automatic recovery units, grease removal devices and other

similar plumbing devices receiving kitchen ows from sinks, oor drains, woks and other food bearing
sources may generate odors. There are many factors inuencing odor evolution and dissemination.

These include room ventilation, kitchen menu, ambient temperatures, ware washing practices, grease/oil

input, daily input uid volume, sanitizers, installation plumbing design and product maintenance/upkeep.
Odors are usually prevented by good area ventilation, frequent uid inputs, good product maintenance

practices and proper product installation. Additional steps, including aeration, chlorination, pH control,
improved area ventilation and additional maintenance may be needed at some sites.

*Devices formerly referred to as grease traps are now called hydromechanical grease interceptors.

3. Plumbing Installation

3.1 Plumbing Considerations Prior to Installation

3.1.1 Locating the Unit

The system should be visible and easily accessible for maintenance and inspection. Options are available
to install the Trapzilla in a basement, suspended from a ceiling or in-ground in an exterior location. Make
sure adequate room is provided around the unit to allow easy access for a pump truck operator. Make
sure the height above the Trapzilla access cover is enough to properly service the system.

3.1.2 Inlet/Outlet Piping

The inlet and outlet piping connections require exible sleeve pipe couplings. Keep outlet piping as

straight as possible. Thermaco, Inc. recommends installation of Two-Way Cleanouts on both the Inlet and
Outlet of Trapzilla Interceptors and Solids Separators in accordance with all applicable laws, regulations
and codes. These cleanouts should match the size of the Inlet and Outlet Piping (i.e. for 4” Inlet/
Outlet piping, a 4” cleanout should be used). Use only “sweep” connections. Do not reduce the pipe
sizing on the outlet piping. Do not install “P” trap on outlet connection of system. (Note: The system
already has a internal gas trap)

TZ-1826 Models

3.2 Vessel Vent Connection

Venting of the Trapzilla tank is recommended by the manufacturer and required for in-door installations.

• Vent the tank through the provided 2” NPT threaded connector on the side of the tank (This vent may
be located above the outlet or on the side of the tank depending on model).

• Remove and discard the plug and connect appropriate vent lines as indicated below (for 2” vent
connection, use 2” pipe).

3.1.3 Flow Controls

Trapzilla systems are supplied with a Low-Head Flow Control module (LHFC). This should be connected

to the inlet of the Trapzilla unit in situations where ow rate needs to be restricted to the ASME rated
ow or when vented ow control is required by local code.

3.1.4 Venting the Outlet

An outlet vent or approved air admittance valve of at least 1/2 the diameter of the system’s outlet
connection must be present as close as possible to the Trapzilla outlet to prevent possible siphonage
problems. The Vent on the Outlet piping is to be installed in accordance with all applicable laws,
regulations and codes. Failure to provide a vent for the system voids Thermaco’s Limited Warranty for
the system.

3.1.5 High Head Height Applications Over Six (6) Feet (1.95 m)

For installations where there is head height of greater than 6 feet (1.95 meters), Thermaco, Inc.
recommends installation of a code-approved Vented Flow Control Assembly (Thermaco VFCA not
included with Trapzilla).

Vessel Vent Connection

Can be connected to the outlet vent,

facility vent, or independently vented to

atmosphere

Note: Drawing for reference only. Equipment must be installed in compliance with all applicable laws, regulations

and codes, including plumbing codes. Installation should be performed by a qualied plumber.
